Too many unfinished requests from your internet network

You see this when you are trying to re-load the page even before its completion, or open several pages at once.
Incomplete requests mean a situation in which the server is not fast enough to generate the page or cancel your request.
It could also mean that the server is overloaded for some reason.
In the history of your requests remain unfinished tasks 5 minutes. Then you may try to reload the page again.

Please mail to petr@neziskovky.com exact explanation what you are trying to do, and I will remove the problem.
